TRANE RunTru central heat pumps: what the model number says

28 models in four RunTru families, 1.5 to 5 tons. On the nameplate, every character of the model number has a meaning in the key Trane publishes: brand, refrigerant, family, efficiency, capacity. Type yours or pick a family: the tool reads it, then sets out what Trane publishes for that family.

Our reading of the figures

Two characters tell you almost everything. The 2nd gives the refrigerant: 5 for the A5HP5’s R-454B, 4 for the R-410A of the other three families. The 5th gives the SEER2 efficiency tier: 3, 4 or 5 in Trane’s current key. Two families sold here predate SEER2: the A4HP6, whose “6” is not in the current key (the 2021 RunTru guide calls it “16 SEER”), and the 2021 A4HP4, whose “4” means 14 SEER, not 14.3 SEER2. Among the pairings on our product sheets, only the A5HP5’s are ENERGY STAR certified, from 1.5 to 4 tons.

04 · Installation

What Trane requires at installation, family by family

The two families whose installation guide we read on Trane’s site. An A5HP5 or E4HL5 installation is checked against these rules.

A5HP5 (R-454B)

  • Trane requires a leak mitigation board in every system, because R-454B is an A2L (lower flammability) refrigerant.
  • R-454B leak detectors only; brazed joints, never soldered.
  • Evacuation to 350 microns or below.
  • Liquid line 5/16 in, no more than 45.7 m in total and 15.2 m of height difference.
  • Where snow builds up, raise the unit 76 to 305 mm and keep the base-pan drain holes open.

Guide ODR-SVX011C-EN (September 25, 2026)

E4HL5 (R-410A)

  • Evacuation to 350 microns or below, after a leak test at 150 psig with dry nitrogen.
  • Liquid line 3/8 in: no more than 30.5 m and 15.2 m of height difference from 1.5 to 3 tons, 50 m and 29.9 m from 3.5 to 5 tons.
  • Copper conductors only, on a dedicated circuit for the E4HL5.
  • Defrost lasts 2 to 10 minutes, and the indoor fan stops meanwhile.

05 · Did you know

Three details from the RunTru documents

01

The 3- and 5-ton E4HL5 units have a capacity switch: set before installation, it brings them down to 75% (2 or 4 tons, per Trane).

Catalog 22-8301-36; guide 88-E4HL5001-1B-EN, Table 10
02

The A5HP5’s compressor goes into protective lockout at −24.4 °C (−12 °F) and restarts at −19.4 °C (−3 °F).

Guide ODR-SVX011C-EN, Table 15
03

The A5HP5’s casing passes a 1,000-hour salt spray test.

07 · Questions

What people ask us about TRANE central heat pumps

Which one heats in the coldest weather?
The E4HL5: Trane publishes its heating down to −20 °C outdoors. For the A5HP5, Trane publishes a heating range down to −17.8 °C. For the A4HP4 and A4HP6, the Trane documents we could read give no limit. The on-site visit tells you whether electric backup in the air handler paired with the RunTru makes sense.
Which ones are ENERGY STAR certified?
With the indoor units on our product sheets, only the A5HP5, 1.5 to 4 tons, with an A5AHV (ENERGY STAR list checked October 28, 2026, US and Canadian markets). At 5 tons, no pairing with an A5AHV is listed. The E4HL5 with the E4AH5E is not on it, and no record exists for the A4HP4 and A4HP6. The A5HP5 and A5AHV pairings are not rated “cold climate” by ENERGY STAR.
Is there a LogisVert grant?
Only on ENERGY STAR pairings: for a heat pump installed since November 26, 2025, Hydro-Québec requires that certification (LogisVert residential page; participation guide, version 1.10), and the guide excludes replacing only the indoor or only the outdoor unit (p. 14). The guide provides $50 per 1,000 BTU/h of heating at −8 °C: for the A5HP5 from 1.5 to 4 tons, that is about $605 to $1,460, an indicative amount computed on the heat ENERGY STAR publishes at −8.3 °C (Hydro-Québec’s list was not read). Only Hydro-Québec confirms the assistance granted.
Why can’t the A4HP6 be read with the current key?
Because the 5th character of today’s RunTru key gives a SEER2 tier: 3 (13.4), 4 (14.3) or 5 (15.2). The A4HP6’s “6” comes from the SEER era: the 2021 RunTru guide calls it “16 SEER”. The rest of an A4HP6 number reads normally.
R-410A or R-454B: what changes?
The global warming potential: 470 for the A5HP5’s R-454B, 2,088 for R-410A, per ENERGY STAR. And the installation: R-454B is an A2L refrigerant, so for the A5HP5 Trane requires a leak mitigation board, detectors made for R-454B and brazed joints.
What warranty comes with a RunTru central heat pump?
Per RunTru, the limited parts warranty lasts, in most cases, 5 years, or 10 years if the unit is registered within 60 days of installation (RunTru line: 1-855-956-5685). Labour is not covered by Trane; AirGreen guarantees it for 6 years on installations done since October 5, 2026.
What RunTru size for my house?
The on-site visit sets it: we look at the house, the insulation, the ducts and the indoor unit in place, and the written quote gives the RunTru family and the size, from 1.5 to 5 tons.
